The Schedule fefen'ed'to in these Letters Patent and making part of the same I, Gor'rmnn MAULICK, of Trenton, county of Mei" the said detachable tooth with a spring retaining catch, so disposed of that itwill form a continuation of the upper edge of the tooth.

Description of the Accompanying Drawing.

Figure 1 represents part of the blade of a circular saw with my improved detachable tooth, and

'Fignre 2, a transverse section on the line 1 2, fig. 1; General Description.

A represents part of the saw-blade. and

B the-detachable tooth.

On the periphery of the blade are formed as many projections, D, as the saw has 'to be furnished with teeth, and the portion d of the projection is gradually reduced in width toward its outer end, so as to, have the slightly tapering form shown, the exterior end of the projection being rounded, andthe whole being adapted to the tapering recess of the tooth D, so that when the latter is fitted to its place, the ends of the prongs e e will bear against shoulders f f on the pro.- jection D; the rounded ends of the portion d of the latter bearing against the ends of the recess in the tooth.

A V-shaped groove, shown in dig. 2, .is formed in: the edges of the recess of the tooth and in the ends of the prongs to receive the U-shaped rib. formed in all parts of the edge of the projection I), with which the tooth is brought into contact.

A notch, in, is formed in the upper edge of the tooth to receive the end not the springcatch ]11, the tooth being recessed to receive this spring, so that the upper edge of the latter will form a continuation oi the nppr edgeof the tooth.

The spring terminates at the rear, in a dovetailed enlargement, fitted and secured into a dovetailed recess in the projection D of the blade.

The tooth can be readily removed after raisingthe end of the spring catch, and the latter willbe selfadjustiug to its proper position on fitting the tooth to the projection, and will effectually retain the tooth in its place.
